Answer:
The correct answer is 61.
Step-by-step explanation:
Undergraduate enrollment at Stellar University in the year 2010 was 2720.
Undergraduate enrollment at Stellar University in the year 2015 was 3025.
Therefore in two years there was a (3025 - 2720 =) 305 increase in number of students at Stellar University.
We have to relate a linear model for enrollment over time. Let y be the enrollment and x be the time.
The linear model would look like y - 3025 = ( x - 2015)
Thus the slope of this line is given by = 61.
Answer:
x = 3
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
(3x + 3 + 4x + 2) = 13
(7x + 5) = 13 ( multiply both sides by 2 )
7x + 5 = 26 ( subtract 5 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
